ELEVATOR AN D STACKER.

SPECIFICATION forming part of Letters Patent No. 464,530, dated December8, 1891.

Application filed February 12, 1890. Serial No. 340,211. (No model.)

To all whom it may concern.-

Be it known that we, GUSTAVUS J. STATES and GEORGE E. HALL, bothcitizens of the United States, residing at Lincoln, in the county ofLancaster and State of Nebraska, have invented a new and useful hood forelevators and stackers for elevating light substances, such as hay andstraw, and especially for such machines as thrashing-machines, whichhave one elevator deliver the substance being handled to another, whichcarries it still higher and farther, of which the following is aspecification.

The object of our invention is to prevent the substance being handledfrom being carried away by the wind or any other cause while it fallsfrom one elevator to another, even though the elevator or stacker whichreceives from the other is continually swinging to and fro. We attainthis object by the mechanism illustrated in the accompanying drawings,in Which-- I Figure 1 is a side elevation of a section of athrashing-machine straw-elevator and swinging stacker in an elevatedworking position, with the hood and receiver-shield attached and showingthe manner of and means for adjusting the hood. Fig. 2is a sideelevation showing a section of the two elevators or stackers as theywould be when let down quite low, with the hood and receiver-shieldattached in their proper working positions. Fig. 3 is a side viewshowing the hood in its proper position, with the elevator and swingingstacker raised and the swinging stacker swung around to a quarteringposition. Fig. 4 is a side view showing the hood and the upper part ofthe elevator folded back onto the lower part of elevator. Fig. 5 is aside elevation showing the hood attached to elevator 1 in position towork in combination with elevator 5 without the use of the receiver 4 inFig. 3. Fig. 6 is a plan view of the receivershield and the lower bowsof the hood. Fig.

7 is a plan View of that bow of the hood which is hinged to the sides ofthe elevator 1. Fig.

8 is a plan view of the'upper bow or bows of the hood.

Similar numbers refer to similar parts throughout the different views.

The hood 3 is constructed of a series of bows, with canvas or othersuitable material stretched from one to the other either on the insideof the bows, as shown in Fig. 1, or on the outside, as shown in Fig. 2.The lower bows 11 and 12 of the hood 3 are so constructed as to form aperfect or nearly perfect circle, as shown in Figs. 1-, 2, and 6; orthey may be constructed with their front and rear parts (either or both)flattened or extending straight or nearly straight across, as shown inFig. 6. The bows 13 and 14 are made straight for a short distance attheir ends, and then they extend around from one side of the elevator tothe other in a semicircular form; or they may be so constructed as toform a short curve on each side a little in front of the end of theelevator and then extend straight or nearly straight across, as shown inFigs. 7 and 8. The bows are all secured to each other by meansof thecanvas 10, which is stretched from one to the other.

The hood 3 is hinged to the elevator 1 by means of a stud, bolt, orother suitable device secured ad justably or stationary to each side,

of the elevator lvnear its upper end,and said studs or bolts (which arereferred to by Fig. 6 in the drawings) pass through holes in the bow 13at or a short distance from its ends and through holes in the ends ofthe bow 14, or the hood 3 may be hinged adjustably to the elevator 1 bythe bolt or stud 16, passing through a small roller resting in the slotin ends of bow 13, and when the hood has been adjusted forward orbackward to the desired position it may be held there by the use of athumb-nut on the end of the stud or bolt 16. When the hood is attachedadj ustably to the elevator 1, as above described, the how 14 should behinged to the bow 13 a little in front of the point where the bow 13 ishinged to the elevator, or they may be always connected in this way.(See Fig. 4.)

The swinging stacker 5 may be provided with a receiver-shield 4, bymeans of which the wind is prevented from blowing up into the lower endof the hood, which would pre- Vent the straw from falling freely on thestacker 5. Although the receiver-shield is a very useful device, yet itis not entirely necessary for the successful working of the hood,

ICC

and therefore it may be dispensed with, (see Fig.:4;) but by its use, incombination with the hood, the hood is sure to work perfectly under allcircumstances.

The above-mentioned receiver-shield is constructed as follows: The lowerloop 7 of the receiver may form a perfect or nearly perfect circle, orit may be cut away on the upper side, so as not to extend across theelevator or stacker, as shown in Fig. 6. The loop 7 is secured to thestacker 5 by means of the strap iron or braces 8 at the sides and 9 atthe rear. To the loop 7 is secured the upper edge of the canvas 6, whichhangs down and may be secured at its lower edge to the side and endboards of the stacker 5. When the receiver 4 is so constructed that itextends across the stacker at its upper part, as shown in Figs. 1 and 2,this part of the canvas should hang free at its lower edge and maybeslitted upward in a few places, so that it will not prevent the strawfrom passing under it,even though it come in large quantities. As thehood 3 is secured to the elevator 1 by means of a hinged bearing, it maybe tilted and held in any desired position by means of the rope 15,which is secured to the upper part of the bow 14. and extends back tothe upper part of the machine. hen the rope 15 is drawn backward, theupper part of the hood is drawn backward and upward and the lower partof the hood is drawn forward, giving the lower edge of the hood a moreslantingposition, thus making it better adapted to operate with theswinging stacker when said stacker is in certain positions. The hood 3and the upper part of the elevator 1 can be folded back upon the lowerpart of the elevator or upon the machine (which is usually done when themachine is to be moved) by the operator at the machine pulling on therope 15, the manner in which the hood folds together being shown in Fig.5. The upper part of the hood is prevented from being drawn backwardonly a certain distance by the lower end of the bow 13 swinging back andstriking the projecting ends of the cross-bar 20 of the elevator, (seeFig. 1,) and if the operator continues to pull the rope backward afterthe ends of the said bow come in contact with cross-bar 20 the hood andupper part of the elevator can both be drawn over backward together. Theweb 2 of elevator 1 is guided over the lower rear edge of the hood bymeans of the shoes or guide-plates 17 ,which are secured to the elevator1 by means of the supports 18. The guide-plates 17 serve also to preventthe rear portion of the hood from swinging up and catching the web 2. Bythe use of the strap 19 the lower part of the hood may be permitted toswing forward and backward, as desired, (as when the hood is beingtilted,) and prevented from going only a certain distance downward. Thecanvas 10 extends below the lower bow or hoop of the hood far enough sothat its lower edge will always be below the upper edge of the receiver4 or the side boards of the stacker 5 when no receiver is used, thusforming a sort of skirt, by means of which the straw or whateversubstance is being elevated is conducted to the stacker 5 without itsbeing aifected by the wind. The lower edge of the skirt of the hood maybe slitted, so that the straw can pass out under it freely, even if itshould come in bunches.

hat we claim as our invention, and desire to secure by Letters Patent,is as follows:

1. The combination, with the elevator, of a flexible hood secured to theupper end of said elevator, the lower end of such hood being circular incross-section, a stacker arranged in connection with the elevator andhood,aud a circular receiver or guard attached to the lower end of thestacker and adapted to encircle the circular end of the hood,substantially as shown and described. 2. A flexible hood for an elevatorand stacker, the said hood being provided with slotted slides to whichthe ends of the upper how are pivoted, and bolts and thumb-nuts wherebythe said upper bow may be adjusted, substantially as specified.

An improved hood for stackers or elevators, comprising the essentiallyU-shaped upper pivotal bows, the lower circular bows, and the canvascovering attached to said bows and connecting the same to form acomplete hood, substantially'as shown and described.

4:. In combination with the hood 3 and elevator 1, the shoes or guides17, and supports 18, as and for the purpose specified.

5. In combination with the hood 3 and'elevator l, the guides 17, thesupports 18, and the adjustable strap 19, substantially as shown andspecified.

6.
